Systems and methods for statistically analyzing apparent CGH Data Anomalies

摘要

Methods, systems and computer readable media for statistically analyzing apparent anomalies in CGH data, wherein the CGH data is ordered corresponding to locations of matter on chromosomes from which the CGH data was derived. A set of CGH ratio values is considered and Z-score values (106) are computed for each CGH ratio value. The Z-score values are classified (108) based upon a predetermined cutoff value. The number of Z-scores that are greater than the predetermined cutoff value are counted, the number of Z-scores that are less than a negative of the predetermined cutoff value are counted, and the total number of Z-scores are counted. A subset of the set of CGH ratios are considered, being defined by a window of predetermined size. A secondary Z-score (116) is computed to measure the significance of at least one of overabundance and underabundance of at least one of significant positive deviations and significant negative deviations in the subset.
